Feature Layer 'Where' property

CurtThue — Fri, 18 Jun 2010 21:58:56 GMT

I have a feature layer that I set the Where property to criteria similar to this:

myFeatureLayer.Where = "FieldName IN ('value1', 'value2', 'value3')";

This worked until I decided to scale it up. If there are 100 values in the criteria it works fine, but once I exceed 100 then IE 8 raises an error (copied below).

In FireFox 3.0.4 it appears fine, also the same value set to a Query Task Where property works.

IE8 error:

Looks like you run into an IE limitation : the Url lenght must be less than 2083.

The Firefox limit is much higher and the Query Task works because the request is automatically forced to POST when the Url is too long.

So what is the work around??? Is there one?

The 2.1 version has no more this limitation. So the workaround is either not to use IE, or to use ArcGIS SL 2.1.
